Board fell on my head a month or so ago. About two weeks ago had a sore bump on my scalp just above my ear. Soreness went away but still have a hard bump. What's concerning me is 2 days ago I just got another hard bump(very simular to the previous described one) about 2-3 inches away, towards the base of my skull. It is also "painful/sore" with, and without, touch, as well as giving me slight headaches. Any ideas what might be going on?
